“Quality work and professional team. I looked around the Stafford area for someone that could replace two of my patio doors with quality doors and Sunshine exceeded my expectations, and trust me, I have very high expectations. Highly professional from start to finish. The gentleman that installed the doors was very meticulous and ensured every minuscule adjustment was perfect.

“We were very happy that we chose Sunshine Contracting for our Hardie siding and gutter installation. Sunshine is one of the few James Hardie Elite Preferred contractors in the area, and they beat the other Elite Preferred installer by about 25 percent on their estimate. More importantly, Sunshine did an awesome job with the actual siding project, board and batten siding on a mid century modern Deck House.”
